PRESSBOARD FOR VELVET, ETC

Y My invention relates to improvements in what are commonly calledpressboards used for pressing velvet, velours and other nap or pilefabrics such as set forth inmy former Patents Nos. Re. 16,194 and1,485,825. l i

These devices comprise multiply `woventextile -fabric foundations havingwire pins vsecured therein. These wires are usually ofwsteel andfrequently rust out under the alternate steaming and drying to whichthey are subjectedin use.

The pins are frequently displaced when` pressure is applied unlessasuitable support Vis, provided Vsuch as a wire meshwork stitched to thecloth foundation. This is satisfactory for many cases but the stitchingis expensive if done properly. If not done properly, the stitchingdisplaces `the pins so as to leave a pattern of the displaced pins onthe fabric which is pressed on `the board.

lThis stitching also sometimes rotsor rust's out or is otherwisedestroyed.

I- also sometimes employ tubular members to permit the passage of steamthrough the foundaf-v tion and it is diicult to hold them inl-place.

After many years of experimentation and study Ihave discovered thatthese dicultieslmaybe solved by securing the wire loops of adjacent pmsy together at the yback of the cloth foundation by soldering,` brazingor welding. m p 1 Figure 1 is an enlarged fragmentary section of apressboard embodying one iforml'ofI my invention.` l M l Figurel 2 is aview of the baclrfof` the same device, parts `being broken away. p

The foundation 'l is usually formed of a number of layers of fwovencotton duck stitched or cemented together. `The points of the pins 8 areinserted through thefoundation leavingthe loop portionsv 9 at the backand resting against They are usually arrangedmalong inclined lines asshown in Fig. 2; The eyelets or tubular `members lll are the' surface`of the vrearmost-` layer.

inserted from the' back betweenrows4 of pins leaving their flanges atthe back. A fine mesh wire ll may be applied to the vback to hold thepins and tubes in place. l

The anchorage of the pins may be effected in several ways. Forinstancebyl applying solder l2'along thelines of the pinloops connecting saidloops. "I'his not onlyreinforces the pins a and holds them in place butcoats them so that suitably impregnated with the protective compins toeach other and to the wire meshwork.

` posed on the opposite face thereof, a layer of wire'mesh covering saidloop portions and oppo- `site faceof the foundation and a coating ofsolder 'over said wire mesh whereby said wire mesh and l vthere is nodangerof theirrusting where the y solder'is applied. I l v rIhe wiremesh maybe soldered, brazec'l` or weldedto the backs of the pins so asto hold them securely in place. `5

A suitable paint or coating compoundl3 may f be applied to thefoundation between the rows thepins so as to assist in preventingcorrosion` or rusting of kthe wires. The y. fabric` may be pound beforeor afterthe pins are inserted. l

In place` of the strips'of solder l2, I; may apply a layer I4 of solderas indicated in Fig. 3.

. A metallic film or layer maybe applied to the backs of the pins bymeans of Va hot spray l5 so as to permanently; connect the Wires. In allf to it in `which case part of thexspray will pass through the meshworkand unite the, pins and 25 the meshwork. l

A suitable so-called liquid solder or cold'solder or metallic paint orcementmay be applied ,to

the *back of the board either directly to the cloth meshwork (if used)in which latter case the liquid will `penetrate the meshwork and bindthe l I claimz` l l l y l. A pressing device comprising aclothfounvdation having U-shaped needles,` the points of saidy `needlesprojecting" from one face of' said foundation and the loop portionsresting exloopportionsi are connected to prevent displacementr of theneedles, y l x i 4` l '2.'
